Patent DE-3134056-A1 (DE)
Title: Circuit arrangement for monitoring a signal over time
Inventor: KNAUER KARL DR
IPC: G01R19/00
Filed: 1981-08-28
Abstract: In this arrangement, each frequency or amplitude deviation which lasts longer than a predetermined time interval (t1, t2) is to be indicated by an error signal. According to the invention, this is achieved by the fact that the circuit arrangement switches to a first or second switching state in dependence on the occurrence of such a deviation, via a comparator (4) which compares the signal (ue) to be monitored with a reference signal. In the first switching state, recharging processes occur between three capacitors (C1, C2, C3), by means of which processes the third capacitor (C3) is charged up step by step. If the deviation persists beyond the time interval, the third capacitor (C3) reaches a state of charging which leads to an error signal. If the deviation disappears within the time interval, the arrangement switches to the second switching state in which the capacitors become discharged. The field of application includes an FM modem of a videotex system. <IMAGE>

Patent DE-3148823-A1 (DE)
Title: Corner connector for profiles which are cut mitred
IPC: E06B3/98
Filed: 1981-12-10
Abstract: During the production of closed frames, the profiles which are cut mitred are intended to be connected to one another as far as possible in a force-fitting manner and as tightly as possible in the mitred corners. A corner connector, which consists of two angle pieces, is provided for this purpose in the region of the mitred corner, within the profiles. As a consequence of recesses in in each case one of the limbs, the two angle pieces can be mutually interleaved. In one of the limbs, each angle piece has a threaded hole into which a clamping screw can be screwed, which clamping screw abuts against the opposite limb of the other angle piece. In this way, the relative positions of the two mutually interleaved angle pieces can be varied with respect to one another, the inner limbs carrying out a movement on the mitred corner. The limbs are connected to the inner wall of the two associated profiles such that the movement is transmitted to the profiles, which are thus pressed together on the mitred seam.

Patent DE-3206640-A1 (DE)
Title: Device for compensating for static measuring-bridge detuning
Inventor: KUNZE JOHANN-GEORG ING GRAD
IPC: G01R17/02
Filed: 1982-02-24
Abstract: In rail contacts for locating railway vehicles and in weight transmitters for vehicle weighing devices which operate with strain gauges (DMS) arranged at the track, the problem is that these strain gauges also respond to static loads such as, for example, mechanical stresses in the rails. The device according to the invention is used for compensating for these static influences during the evaluation of the measurement voltages supplied by the strain gauges. For this purpose, the strain gauges are included in bridge circuits (MB) which can automatically be calibrated again when detuned by static influences. As a reference quantity for this, a voltage value for the expected nominal output voltage of the measuring bridge, stored in a memory (SP1) is used when the track device is not affected, and the current instantaneous value of the bridge output voltage (UDMS), which is also stored in a memory (SP2), is used when a vehicle wheel has stopped on the track device. Any difference between the relevant reference quantity and the current output voltage of the measuring bridge, which can be cyclically retrieved, is detected via comparison devices (V1, V2) and converted into a signal for compensating for the measuring bridge detuning which has occurred. This is done by varying a measuring bridge resistor (R3, R, T) in one or the other direction.   <IMAGE>

Filed: 1982-04-02
Abstract: The invention relates to a terbium-activated yttrium oxysulphide fluorescent material for X-ray intensifier films. For use in medical X-ray diagnosis, it is detrimental if the fluorescent material to be used phosphoresces. On the contrary, it should be free of phosphorescence with undiminished good conversion of X-rays to light. To achieve this aim, the invention proposes an yttrium oxysulphide fluorescent material which is activated with terbium and contains additives comprising activating amounts of niobium and gadolinium. A fluorescence material of this type improved according to the invention is particularly suitable for use in X-ray intensifier films for medical X-ray diagnosis. <IMAGE>

Title: Infinitely variable hydrostatic positive displacement machine
Inventor: KOERNER HELMUT
IPC: F16H39/04
Filed: 1982-04-29
Abstract: The subject-matter of the invention is an infinitely variable hydrostatic positive displacement machine with gearwheels as displacing bodies in internal mesh, in each case in the form of an internal gear and an external gearwheel. As a combination of a pump and motor to give a hydrostatic transmission, the machine makes possible a high performance for many driving tasks. The continuously variable control is effected by adjusting the pressure-oil flow rate by adjusting the width of engagement on the displacing gearwheels, which can be displaced axially relative to one another for this purpose. In the machine, a pumping part with an internal gear and an external gearwheel is assigned an adjoining pressure-oil-driven part with internal gear and external gearwheel in a common housing. At least one of the two internal gears or of the two external gearwheels is here axially displaceable relative to the partner gear for adjustment of the transmission. In addition, each pair of gearwheels displaceable relative to one another has a spur gear providing a sliding seal over the entire extent of meshing, in circumferential engagement with the associated internal gear and in front-face contact with the associated external gearwheel.
